SPECIFICATION forming part of Letters Patent No. 629,316, dated July 18, 17899. Application filed March 1l, 1896. Renewed May 23, 1828l Serial No. 681,502. (N0 mded To all whom it may concern: I

Be it known that we, WARREN C. EVANS, of Exeter, county of Rockingham, State of New Hampshire, and HENRY D. ALLARD, of Bradford, county of Essex, State of Massachusetts,

have invented an Improvement in Sole-Edge- Blacking Machines, of which'the following description, in connectionwith the accompanying drawings, is a speciiication, like vletters 1o and gures on the drawings representing like' parts. I

This invention has for its object the production of a machine for blacking or coloring the edges of boot and shoe soles rapidly and accurately with an even coating of any de'-l sired density, means being provided to absolutely prevent the coloring-matter from touching the upper or the stitches in ,Vfair-stitch' work, the 'eiective 1widthjof the device for' zo applying the coloring-matter being adjustable for soles of different thickness.

Other features of our invention will be hereinafter fully described in the specification and particularly pointed out in the claims.

i Figure l in elevation represents a sole-edge blacking or coloring apparatus embodying our invention. Fig. 2 is a vertical sectional View of one of the blacking-reservoirs, show-T ing the means for insuring the flow of the ina4` 3o terial.- Fig. 3 is a transverse sectional view thereof, taken on the irregular line .fr at, Fig. 2, looking down Fig. 4 is a vertical sectional view of the brush-holder and guard or shield. Figs. 5 and 6 are inner side views of the shields 3 5 shown, respectively, in Figs. 2 ande; andFig.

7 is adetail showing the plunger-lifting mechanism in end elevation, to be described.

The apparatus is shown in Fig. l as mounted upon a frame A of suitable shape'to support 4o the operative parts, having bearings A for a main driving-shaft B, held from longitudinal movement bya triple pulley b b b2 and a cam BX, rotationbeing.transmitted to the shaft byabelt (nct shown) appliedto pulley b. To the'outer end of the shaft B we attach, by a suitable screw h3, a disk D, Figs. ll, 2, and 5,

of less diameter than the circularbrush or Wheel d, mounted on a collar b4 on the shaft adjacent the disk and held in place by a pin 5o 2 on the collar entering a nick in the brushhub. The innerface of the disk-like guardV D is concaved, as' at dx, and provided witha series of peripheral scallops or notches d', as clearly shownv in Fig. 5, to permit the coloringmatter to properly ow to the circumference of the brush when in use.` An annularlyilanged disk d2 iszmounted on and longitudinally movable relative to the shaft B, with its flange d3 adjacent to the brush, said disk being held from rotation by a forked clip d4 6o embracing the vgrooved hub d5 of the disk, thev clip being erected rotatably upon an adjusting-screw-D? Fig. 1

. i The screw DX enters a threaded bearing A10 of theV frame', rotation of said screw by means 65 of its head 5 lmoving-it longitudinally, and thereby moving the iianged disk d2 toward or fromthe brush or Awheel d to change the effective width of the latter between the flange d3 andthe guardjD.

The vedge of thedisk D forms a shield or upper guard and alsoa guide for the shoe, the edge being inserted in the crease between the sole and upper.

The flange d3 is interrupted and uptnrned at d5, the opening between the ears @Z6-*permitting the passage of the blacking or coloring-matter from the reservoir to the brush d, as will be described. We have herein shownV a shaft C mounted in bearings A2 of the frame A and provided with a pulley c connected by a belt cX with the pulley b,'said shaft havingfast thereon a cam OX similar in shape to the cam BX, the

shaft C carrying a brush c and a guard'E, 85

and a disk c2, flanged at c3, is mounted to slide on the shaft C. An adj usting-screw EX, mounted in a threaded bearing of the frame A, is connected by a yoke c4 to thehub c5 of the disk c2 to move the latter in order to adjust the width of the brush c in a manner similar to the adjustment of the brushd hereinbefore4 described, the iiange cbeing interrupted and upturned to formthe sidesc6 of l ahood. M A, .r 95- The guard D is used for all plain work and about the shanks of boot and shoe soles, the thin edge thereof being interposed'between the brush d and the upper to prevent application of blacking or color to the latter. With roo fair-stitch work, however, it is necessary to protect not only the upper b'ut the stitching at the top of the sole, and for such work we use the guard E, which has a eoncaved inner face at eX and peripheral groove e', leaving an outer lip e and an inner .lip e2. As shown by dotted lines, Fig. 4, the lip e enters between the upper and sole, and the upper corner of the sole enters the groove e between the lips e and e2, so that the top of the sole is protected. It' any of the coloring-matter should work under the lip e2, it would gather in the groove c and so would not be directed to the fair-stitching.

The two brushes c and cl and their respective guards E and D are mounted on the same frame, as the guard D will be used around the shank whether on fairestitch or plain work, the concaved inner face of the guard in either case being necess-ary to permit free access of blacking or color to the periphery of the brush.

-rod m4 against the action of its spring s.

Each brush has its own reservoir for the blacking or coloring material, the reservoirs and their operative parts being counterparts one of the other, and only one will be described in detail, the reference-letters M nt m', 85e., of one corresponding, respectively, to4

the letters N n n', the., of the other.

The frame A has open seats A16 A17 for the reservoirs M N, (shown as cylindrical and open at their upper ends,) detachably secured in the seats by screws 1'6 17, respectively, and with their lower ends located just above the interrupted portion of the annular flanges surrounding the brushes c and d.

The bottom m of reservoir M has an upturned annular flange m', surrounded tightly by the lower end of the cylindrical body M,

said bottom having a diainetrical thickened portion M2, extended between the sides d of the hood and slotted at m3 over the brush, serving as an outlet for the .contents of the reservoir, as clearly shown in Fig. 2. A valve, shown as a rod m4, is adapted to move longitudinally in the part m2 to close and more or less open the outlet, according to the retraction of the valve, a spring s, connected at 011e end to a fixed part of the frame A and at its other end to the rod m4, normally retracting the latter to open the outlet. A lug or ear m5, fast on the rod m4, is adapted to be engaged by the cani B on the shaft B to at times close the outlet m3holding the valve- The bottom piece mhas secured thereto a bearing m for the inner end of the rod m4 to steady it and prevent twisting, and an adjustable stop, shown as a screw m7 in the frame A, in the path of the said valve-rod limits its i11- ward movement. A piston or plunger m8, vertically movable in bearings m9 in the reservoir M, has a head or piston m10, provided with a face m12, of rubber or other suitable yielding material, to fit snugly within the flange mwhen the plunger is depressed, as by a spring S surrounding said plunger between one of the bearings mfand a collar m13,

adjustable on the plunger. Then the plunger is lifted, its head is raised above the top of the flange m' and a portion of the material in the reservoir can pass beneath the head, so that when the plunger is depressed said material will be positively expelled through the outlet m3, the valve m4 being withdrawn more or less at such time. A collar m14, adjustable on the plunger 'ms above one of the bearings, limits its depression,while another collar m15, fast on the upper end of the plunger, is provided with an offset m1 to be engaged by a cam m17 on a counter-shaft m18, supported in bearings AS of the frame. Rotation is imparted to said shaft by a belt 30 passing over a pulley m19 thereon and over a pulley 030 on the shaft C.

The shaft m18, mounted to rotate in. bearings A4 of the frame and which lifts the plunger ns, has fast thereon a pulley w20, connected by a belt 2O with a pulley m20 on shaft m13, so that rotation is imparted from shaft m18 to shaft als.

An ear m on collar 'm14 (see Fig. 7) receives loosely there through a vertical pin m21, erected on the reservoir M, to prevent rotative movement of its plunger, a similar construction being providedfor the plunger ns of reservoir N.

The cams BX CX, which control the outlets of the reservoirs, are so arranged relatively to the cams m17 n that when the latter are raising their respective plungers the outlets of the respective reservoirs will be closed, and as or just before the plungers are released the cams B CX will permit the opening of the reservoir-outlets to permit the plunger-heads to force the blacking or coloring-matter out and onto the cooperating brushes.

The screw nl, which regulates the inward or opening movement of the rod n4, is reversed in position, as shown in Fig. l, owing to the construction of the frame.

Referring to Fig. 2, we have shown in dotted lines va spur or point m50 on the rod m4 and upturned into the outlet m3, which may be used if the blacking is very thick to aid in keeping the outlet open.,

A greater quantity of blacking or color must be delivered when it is thick than when it is thin, so that if it is thick the full throw of the rod m4 is permitted, while if it is thin the extent of outlet-opening is regulated by the screws m7 n? to decrease the throw of the rods m4 n4.

The reciprocation of the plungers and their heads serves to agitate or stir the contents of the reservoir when the apparatus is in use.

Shields R R are secured to the reservoirs to project over and partially cover the brushes to protect the operative and the workfrom spattering of the blacking as it is delivered to the brush.

The operator holds the boot or shoe in his hands and with the edge of the guide in the crease between the sole and upper presses the edge of the sole against the edge of the IOO IIO

62eme a evenly and rapidly to the sole edge as it is turned to present new portions to the brush,

the guide also acting as a guard to protect the upper most edectually.

Our invention is not restricted to the precise construction and arrangement 'herein shown and described, as the same may be modified and rearranged Without departing from the spirit and scopeof our invention.

Having f u'lly described our invention, what .We claim, and desire to secure by Letters Pat-1 ent, is- Y l.
